Sound Level Meter Reader with HD Backlit LCD Decibel and Ambient Temperature Meter, Sound & Noise Meter SPL Tester with Alarm, Fast/Slow, Data Hold, MAX/MIN, Auto Power-Off for Noisy Neighbors Office
【High Precision Sensor】The sound decibel meter has a measurement range of 30-130dB, an accuracy of ±1.5dB, and a resolution of 0.1dB. The SPL meter uses a condenser microphone with a frequency range of 31.5Hz to 8.5kHz, providing more professional and reliable data for home and work environment monitoring
【Alarm & Temperature Readout】Built-in adjustable alarm alerts you when noise exceeds your preset level – perfect for maintaining quiet classrooms or monitoring noisy neighbors. Also reads ambient temperature (°C/°F) so you can track room conditions with one device
【Fast/Slow Response & MAX/MIN】Fast response (125ms) captures fluctuating noises like construction or music; slow response (1s) measures steady ambient noise. Use MAX/MIN to record peak sound levels, and Data Hold to freeze current readings for easy recording
【A-Weighted Measuring】A-weighting simulates human ear response for low‑intensity noise like conversations or HVAC systems. Select the right mode to match your specific testing environment
【Portable & Wide Application】Lightweight pocket-sized design with backlit LCD screen – easy to read in dim light. Ideal for classrooms, noisy neighbors, factories, baby rooms, home theaters, audio systems, and construction sites. Includes windscreen ball and carry case
